Yo...
If you haven't checked this vid out of M.Aitken walking out of the therapy center in Utah, please do. Mikey, arguably the BEST rider in BMX had a small "get off" in PA and it resulted in him suffering some serious trauma. Listen to what he says at the end of the interview when asked if he's gonna ride again..."Yes, but with a helmet this time". Think you got more skills than Aitken and don't need a helmet? Don't be stupid.
Check out the vid here. Scroll down to "Aitken Update".
